Electric and Magnetic Fields MS-PS2-3

Electric charge

A measure of the net positive or negative particles in an object. Electric charge. Electric charge is the property of particles that causes them to attract or repel each other.

Electric current

A flow of electric charge, it is measured in amperes A. Electric current. In simple terms, electric current is how fast electricity moves through a wire or circuit.

Electromagnet

A temporary magnet made of wire coiled around an iron core. Electromagnet. An electromagnet is a magnet created by electricity flowing through a wire coil, often wrapped around a metal core.

Insulator

A material that does not let electricity pass through easily is called an insulator. In simple terms, an insulator is a material that stops electricity from flowing, like rubber or plastic around wires.

Magnetic field

The area around a magnet where its magnetic force acts is called a magnetic field. A magnetic field is the invisible space around a magnet where it can push or pull on other magnetic objects.

Magnetic pole

The part of a magnet where the magnetic force is strongest magnetic pole. A magnetic pole is where a magnet's pull or push is the strongest.
